About ILUMYA
What is this medication?
ILUMYA is a prescription medication used to treat adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. It belongs to a class of drugs known as interleukin-23 antagonists, which work by targeting specific proteins in the immune system that contribute to skin inflammation. By inhibiting these proteins, the medication helps to clear the skin and reduce the appearance of red, scaly patches associated with the condition.
The treatment is administered as an injection under the skin, usually by a healthcare professional in a medical setting. After the initial starting doses, the medication is typically scheduled once every twelve weeks for ongoing maintenance. Patients using this therapy are monitored by their doctors for potential side effects, including the risk of infections, as the drug influences how the immune system responds to certain triggers.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
